Hi,
The battery has been fully tendered with a 12.7V reading from my meter and bought a topdiag tool as well... when I turn the key I pretty much get the same reading. Not sure if there is any better way to do load testing.
The bike was able to start with almost zero issue before. I usually let the starter relay getting stuck to let me know the battery is going.
The only changes have been since it last run was maintenance. Replaced the plugs and changed the oil ( main, trans and final drive ) and now it's more dead that its ever been.
At one point after jiggling the ignition switch, I did see the lights come on, hit the starter and then that's when I think I heard the auxillary fuse blow ( 3rd from the bottom )... not sure, but it didn't trigger the starter. That's why I tried to clean the ignition switch, which involved drilling out the little painted over screw since it was so old and stripped the minute I attempted to use a small screwdriver. I cleaned it thouroughly... but honestly, not sure how to test that thing. I did replace the fuse.
Been trying to test grounding all around where I can, pulled the tank off, checked the central grounding area.
The wiring diagrams in both manuals I have are pretty daunting when you really have no idea where to start and the clock dying when I turn the ignition felt like an easy ground thing.
Last time I had issues with the starter relay, I replaced the whole wiring harness since it literally melted a ton of wires, bought 3 different starter relays to find out my battery was bad...
Not sure if that is where I should start again, but I am pretty bummed at this point and don't want to give up...
